## Description

Spec-Driven Development MCP Server provides AI assistants with a structured workflow for software development through 10 specialized tools that guide projects from initial specification to TDD implementation. Built by Yuki Yano using TypeScript and the MCP SDK, it enforces a disciplined development process with tools for spec initialization, requirements generation using EARS format, technical design creation, task breakdown, and test-driven implementation, along with validation tools for design review and implementation gap analysis. The server uses a template-based prompt generation system with frontmatter metadata and includes steering document management for maintaining project-wide context and conventions, making it valuable for teams that want to maintain consistent development practices, ensure thorough documentation, and follow structured workflows from concept to code with built-in approval gates and progress tracking.
